分散型ストレージ
特定の企業に依存しないデータの保存方法。
## Content Addressing vs Location Addressing
Traditional storage uses Location Addressing (e.g., 'go to server X to get file Y'). Decentralized storage uses Content Addressing (e.g., 'anyone who has file with hash Z, please provide it'). This makes the web more resilient because if one server goes down, the same file can be retrieved from anyone else on the network who has it, verified by its unique cryptographic fingerprint.

Centralized storage is keeping all your papers in one office building. Decentralized storage is like shredding those papers, mixing them up, and giving one tiny piece to 100 different people. Only you have the magic key to put them back together.
